Is York County, VA in a flood zone?
FEMA's National Risk Index puts York County's flood hazard at the 57.9th percentile nationally — below the national norm for flood hazard — split between inland river flooding (about once every 1 years) and coastal storm surge (about 3.7 times a year). This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires
The raw NFIP numbers for York County would imply over 100% of mandated homes carry a policy, which just means FEMA's structure-count denominator for this county is wrong, not that compliance is unusually good. This is flagged rather than clipped to look normal — details in the data quality guide. Across all residential structures in York County, not just the ones FEMA mandates, 11% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
